Beson – Binary Extended JSON

I would strongly recommend to avoid any direct resemblance to the unsafe and illdesigned BSON format by mongodb which allows objects, js code or datetime being deserialized, whilst this one looks very safe. I'm just not sure yet if BSON allows arbitrary data being added by a MITM attacker, due it's support for primitive data to be encoded directly. This is the major weakness being added to the first JSON RFC in the 2nd.

There are still better designed, faster and more popular binary serialization formats available, such as MessagePack or Cap'n Proto.

BESON, short for Binary Extended JSON. Beson library is similar to BSON format used in mongodb. The major difference between beson and bson is that beson allows primitive data to be encoded directly. Beson is designed to transfer or store data in a binary format, not specialized for database storage.
